Description

  The present invention relates to a technique for easily performing authentication related to content reproduction and the like.

  2. Description of the Related Art In recent years, a television broadcast receiving apparatus that can view content on a network has been provided by providing the television broadcast receiving apparatus with an Internet connection function. Further, in such content viewing and the like, it is often assumed that authentication processing is performed by allowing a user to input information such as a registration ID and a password.

  However, since the input device of the television broadcast receiving apparatus is a remote control device mainly based on 12 numeric keys, for example, the user ID and password for authentication configured including a character / symbol string other than numerals are used. Not suitable for input.

Therefore, Patent Document 1 discloses a technique related to an authentication system that uses a telephone as a physical device for authentication and can authenticate a user by saving the input of a user ID, a password, and the like by a callback for a registered telephone number. It is disclosed. Specifically, first, the user registers a telephone number in the system. After that, when receiving authentication, the user inputs a phone number that can be easily input using only numeric keys. Then, the authentication system checks whether the telephone number matches the registered telephone number, and if it matches, executes a callback to the telephone having the telephone number. For example, voice guidance or the like is performed at the callback, a push button signal is transmitted from the user, and identity verification and usage confirmation are executed.

It is characterized by being able to.

  Second, the code login system of the present invention is also characterized in that the authentication AV code signal is output and displayed on the screen of the AV device as a two-dimensional barcode, for example. . Since the two-dimensional bar code and the like can be easily read by photographing with a mobile terminal, for example, it is possible to save the trouble of inputting the AV code.

  Example 1

    <Overview>

  FIG. 1 is a conceptual diagram illustrating an example of user authentication processing by the code login system of the present embodiment. As shown in FIG. 1A, first, a television apparatus with an Internet connection function, which is an AV (audio visual) apparatus, accesses a server subsystem including a content distribution server on the Internet via a network. Then, a request for viewing “Drama Episode 1” of the distribution content is transmitted. Then, in the server subsystem, in response to the content distribution request from the AV device, for example, user authentication processing for performing content distribution and associated charging processing is executed as follows.

  First, the server subsystem that has received the content distribution request generates an AV code for authentication such as “0123” and converts it into a form that can be output on a television display such as a two-dimensional barcode. Then, as shown in FIG. 1B, the AV code indicated by the two-dimensional bar code is returned to the television display and displayed on the display. And as shown in FIG.1 (c), the two-dimensional barcode displayed on the television display is image | photographed with a portable terminal. Then, the AV code “0123” obtained as a result of the analysis processing of the two-dimensional barcode analysis software incorporated in the portable terminal is transmitted from the portable terminal to the server subsystem.

  Then, in the server subsystem, assuming that the AV code “0123” has been authenticated, processing corresponding to the content distribution request executed in association with “0123” is executed. Therefore, as shown in FIG. 1 (d), it is possible to view a desired content on a television display by further executing a content distribution request from the two-dimensional barcode screen after the authentication processing by the portable terminal. It can be done.

    <Functional configuration>

  FIG. 2 is a diagram illustrating an example of functional blocks in the code login system according to the present embodiment. As shown in this figure, the code login system of the present embodiment includes an “AV device” (0200), a “server subsystem” (0210), and a “portable terminal” (0220). Hereinafter, the configuration requirements of each of these devices and subsystems will be described.

    (AV device)

  First, the “AV device” (0200) includes a “first content transmission request output unit” (0201) and an “AV code output unit” (0202). An “AV device” refers to a device having a function for reproducing and outputting content. For example, an output device such as a music player device including a television display device or a speaker device, or a recording / recording device connected to the output device. Apparatus and various tuner apparatuses for broadcasting.

  Note that the functional blocks of the AV device, the server subsystem, and the mobile terminal described below can be realized as hardware, software, or both hardware and software. Specifically, if a computer is used, a CPU, a main memory, a bus, or a secondary storage device (a hard disk, a non-volatile memory, a storage medium such as a CD or a DVD, and a read drive for the medium), printing Used for hardware components such as devices, display devices, other external peripheral devices, I / O ports for the external peripheral devices, driver programs for controlling the hardware, other application programs, and information input A user interface etc. are mentioned.

  Then, by CPU processing according to the program developed on the main memory, the data input via the interface and stored in the memory and hard disk are processed and stored, and the above hardware and software are controlled. Instructions are generated. The present invention can be realized not only as a system but also as a method. A part of the invention can be configured as software. Furthermore, a software product used for causing a computer to execute such software and a recording medium in which the product is fixed to a recording medium are naturally included in the technical scope of the present invention (the same applies throughout the present specification). Is).

  The “first content transmission request output unit” (0201) has a function for outputting a first content transmission request to the server subsystem (0210). For example, wired / wireless communication for connecting to the Internet. It can be realized by an IF (interface) or its control application.

  The “first content transmission request” refers to information for requesting transmission of content to itself, for example, an HTTP request transmitted via a content distribution Web page being browsed by a Web browser. It is done. FIG. 3 is a schematic diagram showing an HTTP request which is an example of the first content transmission request. As shown in this figure, for example, an HTTP request for requesting to transmit a video content file “drama01.avi” is output by the GET method. The “www.aaa.co.jp” server that has received this HTTP request performs various processes for authentication, which will be described later, before returning “drama01.avi” in response to the HTTP request of this GET method. , And so on.

  The content requested to be transmitted here may be other media data such as a still image, music, and document, or a program such as a game program or update firmware, in addition to the moving image content described above. .

  The “AV code output unit” (0202) has a function of reproducing the AV code signal returned from the server subsystem (0210) in response to the first content transmission request and outputting the AV code. The “AV code signal” refers to an AV code signal output by audio or / and video. The “AV code” refers to a code such as “0123” for indicating a character / number (including symbol) string that is managed and used for authenticating a user in a server subsystem described later.

  Further, the reproduction output form of the AV code is not particularly limited. For example, as described above, if a signal / character string (AV code) for user authentication is converted into a two-dimensional barcode, the two-dimensional barcode is displayed on the display device as shown in FIG. The form which outputs is mentioned. Alternatively, the AV code character string itself may be output and displayed on the display. In addition, in the case of a signal obtained by modulating an AV code into audio data by using acoustic OFDM processing or the like, a form in which the AV code is output by the audio by the speaker device as shown in FIG. It is done.

  The AV code output in this way is read by a portable terminal (to be described later) by means such as photographing or recording, and is transmitted to the server subsystem for use in user authentication.

    (Server subsystem)

  Next, the configuration requirements of the “server subsystem” (0210) that constitutes the code login system together with the “AV device” (0200) will be described. The “server subsystem” (0210) includes a “first content transmission request acquisition unit” (0211), an “AV code signal transmission unit” (0212), and a “comparison unit” (0213). The “server subsystem” refers to a server device on the network for performing content distribution processing, user authentication processing, and the like. For example, the server subsystem may be realized by a single server device, a content distribution server, or an authentication server. Further, it may be configured by a server group that is distributedly constructed according to functions, such as a billing server.

  The “first content transmission request acquisition unit” (0211) has a function of acquiring a first content transmission request from the AV device (0200). For example, a wired / wireless communication IF (interface) for connecting to the Internet. And its control application. In response to the first content transmission request acquired here, the server subsystem executes the following processing for user authentication.

  The “AV code signal transmission unit” (0212) has a function of transmitting an AV code signal in response to reception of the first content transmission request. The “AV code signal” refers to an AV code signal output as audio or / and video to an AV device as described above. Further, the AV code that is a source for generating the AV code signal may be generated using, for example, a random generator each time the first content transmission request is acquired. Alternatively, an AV code table or the like may be provided in advance, and the acquisition of the first content transmission request may be used as a trigger to select an AV code to be used randomly or according to a predetermined rule.

  Then, for example, the AV code acquired by the generation or selection process as described above is converted into, for example, a two-dimensional barcode, or multiplexed into the audio data by the OFDM modulation process to generate an AV code signal, and AV For example, it is transmitted to the device.

  Further, the AV code generated in this way is managed by the server subsystem and processed by adding a flag of “valid” after accepting authentication from a portable terminal to be described later. The user authentication process by the login system is realized.

  FIG. 5 is a diagram illustrating an example of an AV code managed by the server subsystem. As shown in this figure, for example, for each first content transmission request acquired by the server subsystem, an AV code is generated such as “894fe10ad9”, “090eec05d7”, “26f731a9de”, “0598d894ac”, “ac184dfee18”, get. The AV code thus generated and acquired is managed in association with the requested content IDs “drama01.avi” and “drama02.avi”. In addition, as shown in the figure, an authentication Web page URL may be generated and managed for each AV code. This authentication page URL is used as a URL used as an AV code transmission destination in a portable terminal, which will be described later, or as a URL of a Web page for distributing contents by accessing after the AV code is authenticated. Good to be done.

  The “comparison unit” (0213) has a function of comparing the transmitted AV code signal with the AV code included in the login information received from the mobile terminal, and is realized by an arithmetic device such as a CPU or a main memory. be able to. Specifically, the AV code indicated by the AV code signal transmitted as described above is managed in a management table as shown in FIG. 5, for example. Therefore, the relationship between the AV code included in the login information transmitted from the portable terminal described later and the AV code of the management table (for example, complete match, partial match, etc.) is determined by CPU logical operation processing. When a comparison result indicating that both AV codes are completely matched is output by the logical operation processing of the CPU, for example, an authentication flag is added to the AV code in the management table as shown in FIG. Then, regarding the AV code, it is assumed that user authentication has been performed, and content distribution processing or the like is executed in subsequent access including the AV code.

    (Other configuration of the server subsystem of this embodiment)

  Further, a function for authenticating the mobile terminal itself that transmits the login information may be provided before the AV code comparison process in the comparison unit. Specifically, for example, when accessing a web page for authentication for transmitting login information from a mobile terminal, the personal identification number of the mobile terminal is acquired on the web page. Then, the login information transmitted after accessing the authentication Web page is configured to include the individual identification number, and by determining whether the individual identification information matches, the mobile terminal is first authenticated. Then, the AV code comparison process in the comparison unit as described above is executed using the login information from the mobile terminal that has been authenticated. Of course, the authentication of the first portable terminal is not limited to the authentication using the solid identification information. For example, when accessing the authentication web page for the first time on the portable terminal, the ID and password are input and then transmitted. The login information may be configured to include the ID and password, and by determining whether they match, the mobile terminal may be authenticated first.

  For this purpose, the other server subsystems of the present embodiment may further include the following configuration requirements in addition to the above configuration requirements. Specifically, the “server subsystem” of the other code login system of the present embodiment further includes an “initial registration information receiving unit” and an “initial registration result reply unit”. Further, the comparison unit of the server subsystem further includes “registration result comparison unit”.

  The “initial registration information receiving unit” has a function of receiving initial registration information for initial registration of the mobile terminal. The initial registration information includes, for example, the individual identification information of the portable terminal, an ID and a password input when accessing the authentication Web page, and the like. In addition, for example, as described above, there is a method of receiving initial registration information using a Web page such as authentication as described above.

  The “initial registration result reply unit” has a function of holding a registration result in accordance with the received initial registration information and sending a reply to the mobile terminal. Thus, for example, a session is established between the server subsystem and the portable terminal by returning the registration result from the server subsystem to the portable terminal.

  The “registration result comparison unit” has a function of receiving the registration result transmitted to the mobile terminal and comparing it with the stored registration result in the comparison process between the AV code signal and the login information in the comparison unit. . The registration result may be received in a form such as being included in login information as will be described later. Then, by comparing the registration results, the portable terminal itself that transmits the login information can be authenticated before the AV code comparison process in the comparison unit.

    (Mobile device)

  Finally, the configuration requirements of the “portable terminal” (0220) constituting the code login system together with the “AV device” (0200) and “server subsystem” (0210) will be described below. The “portable terminal” (0220) includes an “AV code acquisition unit” (0221) and a “login information transmission unit” (0222). The “portable terminal” is a concept including, for example, a smart phone, a PHS (Personal Handyphone System), a PDA (Personal Digital Assistance) in addition to the mobile phone.

  The “AV code acquisition unit” (0221) has a function of acquiring an AV code output from the AV device. For example, when the AV code signal is output in the form of a two-dimensional barcode in the AV device, the camera function And two-dimensional barcode analysis software for captured images. Specifically, as shown in FIG. 7A, the two-dimensional barcode returned from the server subsystem and displayed on the display of the AV device as described above is captured using the camera function of the portable terminal. To do. Then, as shown in FIG. 7B, the AV code indicated by the two-dimensional barcode is obtained by analyzing the photographed image with the two-dimensional barcode analysis software. Similarly, as shown in FIG. 7, a two-dimensional barcode that is an AV code includes an authentication URL, and the two-dimensional barcode is analyzed so that the authentication URL can be easily accessed. Also good.

  Alternatively, when the AV code character string or the like is output on the display of the AV apparatus or the like, the AV code may be obtained by analyzing the character string by pattern matching or the like.

  For example, when an AV code signal is output as audio data in an AV apparatus, an “AV code acquisition unit” may be realized by a microphone (sound collecting) function or audio OFDM data analysis software.

  The “login information transmission unit” (0222) has a function of transmitting login information to the server subsystem based on the acquired AV code. Here, it is desirable that the login information includes an AV code in order to execute the comparison process in the server subsystem as described above. Alternatively, for example, the captured image itself of the two-dimensional barcode may be transmitted to the server subsystem as login information. In that case, the server subsystem analyzes the two-dimensional barcode image and extracts the AV code.

  In addition to the information indicating the AV code, the login information may include, for example, the individual identification number of the mobile terminal as described above. Alternatively, a simple user ID, password, etc., such as only at the first time, may be input on the portable terminal and included in the login information. In this case, as described above, the server subsystem is configured to acquire these pieces of information in advance at the first access to the authentication Web page. And it is good to comprise so that authentication of a portable terminal may be performed initially by comparing these information contained in login information at the time of subsequent transmission of login information.

  Further, the login information may include the content ID requested to be transmitted by the first content transmission request. In the comparison process in the comparison unit of the server subsystem described above, the AV ID to be compared is determined in order to determine, for example, complete match using the content ID.

  Then, the login information including the AV code and the like is transmitted to the server subsystem and compared with the AV code managed in the management table as shown in FIG. It is done.

    (Other configurations of the portable terminal of this embodiment)

  Further, the mobile terminal may further include the following configuration in order to authenticate the mobile terminal itself that transmits the login information before the AV code comparison process in the comparison unit of the server subsystem. good. That is, the “portable terminal” of the other code login system of the present embodiment includes an “initial registration information generation unit”, an “initial registration information transmission unit”, a “reply result reception unit”, and a “registration result holding unit”. Have. The login information transmission unit of the mobile terminal further includes “registration result transmission means”.

  The “initial registration information generation unit” has a function of generating initial registration information for initial registration of the mobile terminal itself. The initial registration information may be generated by, for example, an ID or password input on the authentication Web page, or an ID or password stored in a flash memory or the like, or a solid identification number is acquired. May be generated.

  The “initial registration information transmission unit” has a function of transmitting the generated initial registration information to the server subsystem.

  The “reply result receiving unit” has a function of receiving a registration result returned according to the transmitted initial registration information. The “registration result returned in response to the initial registration information” includes, for example, information indicating that registration is completed.

  The “registration result holding unit” has a function of holding a received reply result to be transmitted when receiving subsequent authentication from the server subsystem, and can be realized by a storage device such as a flash memory.

  The “registration result transmission means” has a function of transmitting the held registration result together with the login information in the login information transmission process in the login information transmission unit. As described above, a session is established between the server subsystem and the portable terminal by transmitting and receiving the registration result returned and held from the server subsystem, and the AV code is authenticated within the session. It is said that it is done.

    <Hardware configuration>

  8, 9, and 10 are schematic diagrams illustrating an example of a configuration of each device or the like that configures the code login system when the functional components described above are realized as hardware. The operation of each hardware component in the code login process will be described with reference to these drawings.

    (AV device)

  First, an example of the hardware configuration of the AV apparatus will be described. As shown in FIG. 8, the AV apparatus includes a “CPU (central processing unit)” (0801) for performing various arithmetic processes and a “main memory” (0802). Also, a “flash memory” (0803) for storing data and programs, a “remote control receiver” (0804) for accepting operation input from the user, “VRAM” (0805) and “display” (0806) as AV code output units. ), A “communication IF” (0807) which is a first content transmission request output unit. They are connected to each other via a data communication path such as a “system bus” to transmit / receive information and process information.

  A program is read out to the “main memory”, and the “CPU” executes various arithmetic processes by referring to the read out program. In addition, a plurality of addresses are assigned to each of the “main memory” and “flash memory”, and in the calculation processing of the “CPU”, the addresses are specified and accessed to store the data. It is possible to perform arithmetic processing using.

  Here, a “remote control” button operation signal or the like is received by the “remote control light receiver”, and activation of an Internet browser application, access to a desired Web page, or the like is executed in accordance with the operation signal. In response to the access, for example, an HTML document in the content list is returned from the content server included in the server subsystem, and is received by the “communication IF” of the AV apparatus. The received content list is stored at address 1 of the “main memory”, and is displayed on the “display” via “VRAM” by processing according to the content request program.

  The user looks at the content list displayed on the “display” and determines the content desired to be distributed. When the content selection signal input by operating the remote control button or the like is received by the “remote control light receiver”, the “CPU” requests an HTTP request for requesting distribution of the content indicated by the selection signal in accordance with the content request program. (Content transmission request) is generated and stored in address 2 of “main memory”. The content transmission request is transmitted from the “communication IF” with the IP address of the content server as the destination.

  Then, an AV code indicated by a two-dimensional barcode generated in response to the content transmission request is received by the “communication IF” by the processing of the server subsystem, which will be described later with reference to FIG. Store at address 3. Then, an AV code display screen including image data of, for example, a two-dimensional barcode indicating the AV code is generated and stored in address 4 of “main memory”. Then, the image data is transferred to “VRAM”, and the two-dimensional barcode is displayed on the “display”. Then, as will be described later with reference to FIG. 10, for example, a two-dimensional barcode displayed on the display is photographed and analyzed by the “mobile terminal”, and the AV code is used for authentication processing. .

  The AV code returned from the server subsystem may be returned in a form added to audio data by OFDM modulation processing, for example. In that case, the audio data including the AV code received by the “communication IF” is stored in the address 3 of the “main memory”. Then, the audio data is output from a “speaker” or the like through processing of a “D / A conversion circuit” or “acoustic circuit” (not shown). The AV code may be extracted and used by recording and analyzing the audio data output from the speaker by a “portable terminal” described later.

    (Server subsystem)

  Next, an example of the hardware configuration of the server subsystem will be described. As shown in FIG. 9, the server subsystem includes a “CPU” (0911) and a “main memory” (0912) which are comparison units and perform other various arithmetic processes. Also, an “HDD” (0913) that stores data and programs, and a “communication IF” (0914) that is a first content transmission request acquisition unit and an AV code signal transmission unit are provided. They are connected to each other via a data communication path such as a “system bus” to transmit / receive information and process information.

  Here, as described in FIG. 8, the HTTP request (content transmission request) transmitted from the “AV device” is received by the “communication IF”. Then, the server subsystem stores the received content transmission request at the address 1 of the “main memory”, and executes the following processing using the storage as a trigger. That is, first, the “CPU” randomly generates and acquires an AV code using a random function or the like according to the authentication program. Alternatively, an AV code used for authentication is acquired by selecting an AV code from a preset AV code table. Then, according to the authentication program, the “CPU” generates a two-dimensional barcode as an AV code signal indicating the AV code, or generates voice data modulated by OFDM so as to include the AV code. The AV code signal is stored at address 2 of the “main memory”.

  At the same time, an authentication management table associating the AV code and the URL of the authentication Web page as shown in FIG. 5 is generated and held at address 3 of “HDD”. Then, in the server subsystem, subsequent authentication processing is executed as follows using this authentication management table.

  That is, a login including an AV code obtained as a result of analysis of a two-dimensional barcode output and displayed on, for example, a display of the AV device by processing in a “portable terminal” described later in FIG. Information is acquired by “Communication IF”. Then, the login information is stored in the address 4 of the “main memory”, and the content ID included in the login information is specified from the authentication management table shown in FIG. 5 stored in the “HDD”. Then, a comparison for calculating the degree of coincidence between the AV code associated with the content ID and the AV code included in the login information is executed by a logical operation process of “CPU”. For example, when there is an AV code that completely matches in the authentication management table, the AV code is added as an authentication flag, for example, as shown in FIG.

  For subsequent access using the AV code, the “CPU” refers to the authentication flag and outputs information indicating that it has been authenticated in accordance with the authentication program, and sends it to the “HDD” in response to a content transmission request. The stored content is returned to the AV device.

    (Mobile device)

  Finally, an example of the hardware configuration of the mobile terminal will be described. As shown in FIG. 10, the mobile terminal includes a “CPU” (1021) that performs various arithmetic processes and a “main memory” (1022). In addition, a “flash memory” (1023) for storing data and programs, “buttons” (1024) for accepting operation input from the user, “camera” (1025) as an AV code acquisition unit, and a login information transmission unit A certain “communication IF” (1026) is also provided. They are connected to each other via a data communication path such as a “system bus” to transmit / receive information and process information.

  Here, as described with reference to FIG. 8, for example, when a two-dimensional barcode displayed on the display of the “AV device” is photographed by the “camera”, the photographed image data is stored in the address 1 of the “main memory”. The Then, the AV code is acquired from the analysis result of the captured image data of the two-dimensional barcode by the arithmetic processing of the “CPU” according to the login program, and stored in the address 2 of the “main memory”. Similarly, the Web page URL for login is acquired as a result of the analysis of the two-dimensional barcode, and stored in address 3 of “main memory”. Then, an access request to the URL including the AV code is transmitted from the “communication IF” in response to accepting an operation input by the “buttons”. As described with reference to FIG. 9, the AV code is received by the “server subsystem” by the access request, and the authentication of the AV code is executed.

    <Process flow>

  FIG. 11 is a flowchart illustrating an example of a processing flow in the code login system of the present exemplary embodiment. As shown in this figure, first, the AV apparatus outputs a first content transmission request (step S1101). Then, the output first content transmission request is acquired by the server subsystem (step S1111). In response to the acquisition of the first content transmission request, the server subsystem acquires the AV code itself, a two-dimensional barcode converted from the AV code, OFDM voice data, and the like (step S1112). Then, an AV code signal indicating the AV code is transmitted to the AV device that has output the first content transmission request (step 1113).

  The AV device receives the AV code signal returned from the server subsystem (step S1102), and reproduces and outputs the AV code indicated by the AV code signal from, for example, a display or a speaker (step S1103). Then, the AV code output and reproduced by the AV device on the portable terminal is acquired by, for example, photographing or recording (step S1121), and the login information is transmitted to the server subsystem based on the acquired AV code ( Step S1122).

  In the server subsystem, when the login information transmitted from the mobile terminal is received (step S1114), the AV code included in the received login information is compared with the AV code acquired in step S1112 (step S1115). For example, when a comparison result indicating that the two match is output, the AV code is processed as authenticated.
